Hi, my name is Barbara and I am from Conneciticut. I use regular thread when I sew my labels on. I use the color close to the color of the outside edge and I just stitch around the edge of the label. I hope I have myself clear. I sew the same way with the iron on labels as you can't iron them on yarn, unless you put like a white pillow case on top of label and press with steam iron, but I still sew around the label edges. Hope this answered your question. I am still trying to figure out how to post a question I have. I just emailed the forum to have them tell how to do it. Have a great day and good luck with your labels. Barbara Mudd
